Almost nothing, which is why I have come to believe marriage has become a woefully outdated practice in the US at least. However, I am married, and I believe in honoring my promises, so I am in it to stay. The thing is, there are cases where the woman is the bread winner and the man stays at home and tends house and kids. If the spirit of the original tradition is to be honored, the man should actually take the woman's name. Which is why it is an outdated tradition. It was fine when professional men and home economics-minded women were the norm, but that changed long ago.

Wow, this topic went off the rails!
